Point being, if the tumor is small and intracanicular and there is already a minor hearing loss, the average pt. has about 4 years of speech recognition left. There needs to be intervention because even if the tumor volume is not increasing, damage is continuing in the cochlea and along the auditory nerve. Possibly as far as the cochlear nucleus of the brain stem. Given that scenario, a person cannot be expected to do well for very long even with the highly touted cochlear implant. Next stop: ABI.
Dr Williams was thinking outside the box and looking at improving potential outcomes when he perfected FSR for AN at JHH. Sadly, this pioneer passed away. Dr. Lederman may have had his hand in the research also. Certainly, the trials, for good or bad.
Needed, is a neurosugeon willing to step up to the plate and quit following status quo re, AN Tx ( Conservative Management ). I guess, in a way, Dr. Shahinian has tried something different with fair result.
